🚨 Some #NPOs look like independent #healthinformation hubs - but operate as strategic arms of the #F&B industry.

They influence science, public messaging, and policy-makers.

We study 5 cases: ILSI Europe, EUFIC, BNF, FEN, and Austria’s FEH.

I got an email yesterday afternoon that my NSF SPRF Postdoctoral Fellowship was terminated. My grant focused on testing interventions to address online misinformation and I was 8 months into a two year appointment.

Friday Night Massacre of accurate information.

A devastating day for the USA as tens of millions of dollars of grants seeking to combat the spread of false information were terminated. We have a federal govenrment that does not consider the verifiable truth a priority. www.nsf.gov/updates-on-p...

The NIH canceled my research on vaccine hesitancy www.statnews.com/2025/03/28/v... via @statnews

"Each year in the United States, approximately 6,000 people die from influenza.

More than 7,000 will die from Covid-19 in 2025.

...an American child died from measles for the first time in a decade."
The NIH canceled my research on vaccine hesitancy
The decision to end research on vaccine hesitancy is deeply disrespectful of those who have lost or will lose loved ones to vaccine-preventable disease.

So it begins: "Email directs NIH staff to identify grants related to ‘fighting misinformation’."
Honestly, I was a bit surprised that earlier lists of forbidden terms didn’t (yet) include “misinformation” & “disinformation.”
Turns out, they had a separate plan for dealing with that kind of research.

📢Does school education improve #HealthLiteracy? Our data say NO.

We tested 780 Austrian pupils (9–13) using a performance-based HL test.

❌Result: No improvements w/ grade level (fig1).

⚠️Problem: They increasingly rely on unmoderated sources, but aren’t prepared (fig2).

New blog post on #MediationAnalysis (MA), which is widely misunderstood and overused in #CommunicationResearch and #Psychology.

I made mistakes using MA myself, and no one should be blamed. But it's important to discuss flaws, esp. as MA has become so popular.

Why We Should Stop Using Mediation Analysis
"Imagine that a medical research group were to conduct an experimental test of a new drug for dementia, and use mediation analysis…”
